Reading through the posts here, I thought you guys might be interested in checking out this:
The Global Comic Jam ( www.globalcomicjam.com ) is a collaborative website where comic creators from all over the world jam together on 8 stories, one page at a time -- no prepared scripts and no safety nets!

This project is the brainchild of Danish comic artist Kim Larsen, and so far 19 contributors from countries as diverse as South Africa, Australia, Sweden, USA and Jordan have generated over 50 pages with many more to come!
